Just before I go listing stuff, I was thinking, and would anyone else say that "knowing when not to press the shutter" might be the most important aspect to creating a great photo?

But anyway, I posted a journal a few months ago, that listed my comparisons between audio and photography. Looking back on it, I realise that a lot of it is wrong. So here is my revised list.


Straight Analogies:
Shutter = Record Button
Shutter Speed = Relates to the SPL (sound pressure level) of the source at the diaphragm of the microphone.
Focal Length = Relates to Microphone Choice. An Omni mic is an Ultrawide, and going up to a Gun Mic which is your Telephoto
Dynamic Range = Signal to Noise Ratio
Lens = Microphone
Hot Areas = Clipped Signal
Cold Areas = Signal below noise floor
Infrared = Subsonic (DC to 20Hz)
Ultraviolet = Supersonic (20kHz +)
Monochrome = Mono
Colour = 3 Channel Stereo
Noise = Noise
ISO = Gain
Exposure Compensation = Gain (On the Fader)
Resolution = Sample Rate
Fine Detail = High Frequencies
Large Objects = Low Frequencies
Bit Depth = Bit Resolution
RAW = PCM Wave
JPEG = MP3/AAC etc.
Moire = Aliasing (but its also called Aliasing in imaging)
Adjusting Levels = Normalising
Continuous Shooting Mode = Looped overdubs recording multiple takes of the same section
Shifting Black Point Level = Noise Gate


Partial Analogies:
Min. Focusing Distance = You cannot focus a microphone. But get too close to a microphone and you risk damaging the diaphragm, so it could relate to this.
Aperture = Also relates to the SPL of the source, and the balance between sources. It could be viewed directly, so perhaps would be similar to placing a parabolic reflector behind the mic that increases the level of sound reaching the diaphragm
High Dynamic Range Image = Comping perhaps, but what its really doing is what a compressor does and squashes the dynamic range
Metering (in general) = Pre Fade Listen
Reviewing Photos = After Fade Listen


Farfetched:
AF = Doesn't exist. You cannot focus a microphone. But our ears can focus, so this could relate to the portion of our brain that deals with sound
White Balance = Could relate to subjective factors such as how 'Bright' a recording sounds
Sensor Dimensions = Could relate to the size of the microphone diaphragm, but a large diaphragm microphone has poor high frequency response, unlike a larger camera sensor, so I don't know with this one
Flash = It has a similar effect to moving one sound source closer to the microphone in comparison to others, but I cannot think of an analogy for this one


I was also wondering why we can't use digital systems for photography to re-create the exact original, like we do in audio. Then it hit me that the resolution of the human eye (somewhere in the region of 600 Megapixels) is far harder to replicate than the resolution of the human ear (with 20kHz being an easily attainable frequency), and to the resolution of the camera, the result is an exact representation of original. My bad...
